Composite Windows Could Cut Costs

14 January 2010

A new research project aims to use composite materials in order to eliminate thermal bridges, condensation and mould in our living rooms.

By designing a new generation of high insulation windows, researchers aim to significantly reduce the amount of heat lost from our homes.

More than one third of the energy used to heat buildings is lost through windows and doors. Frames and sills are the principal offenders as they are less insulation-efficient than the glass itself. As a result the European building industry is under pressure to develop windows that will reduce the energy loss from buildings and thus also reduce carbon emission.

The project, a partnership between Fiberline Composites and the Civil Engineering and Mechanical Engineering departments of Denmark’s Aalborg University, aims to develop composite window frames that have twice the insulation efficiency of the very best frames and sills currently on the market.

“Our goal is to achieve a technology shift by substantially enhancing the insulation performance of window frames and sills, while at the same time creating ultra-slim, high-strength windows, doors and facades that require no maintenance,” says Peter Thorning, Chief Innovation Officer at Fiberline Composites.

“The new technology will be made available to European manufacturers of windows, doors and facades who will be able to use it to produce windows that make it cheaper to insulate both new and existing buildings. They will also be able to create their very own design solutions,” adds Thorning.

The Danish National Advanced Technology Foundation (HTF) is providing funding of DKK 5.8m to the research project over a period of three years.
